Since out templates volume is always increasing keeping up demo docs fresh and up to date has become an issue.

I have currently written all those articles in plain html format.
Does anyone know a simple way to pull these inside Joomla?

The idea is to keep them all on our framework website and when user visits the demo the html pages are pulled from our framework site in to Joomla. This way we can always update one set of files instead over 100+ demos.

The issue is that those pages should be processed trough Joomla if possible as Joomla articles.
